JOHN A. KIENARDT, OF DAYTON, OHIO, ASSIGNOR TO G. H. GEIGER, OF SAME PLACE.

SLATE-ERASER.

SPECIFICATION forming part of Letters Patent No. 371,589, dated October 18, 1887. Application filed March 29, 15 86. Renewed July 23, 1887. Serial No. 245.07 1. (No model.)

T all whom it may concern.-

Be it known that 1, JOHN A. KIENARDT, a citizen of the United States, residing at Day ton, in the county of Montgomery and State 5 of Ohio, have invented a certain new and useful Improvement in Slate-Erasers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in 1 slate-erasers; and it consists of a hollow ves sel with a small orifice in the solid end, and the other is filled with a plug, and to which ends are attached sponges or other suitable substances, and at the longitudinal center of said vessel is a stopple, which also serves as a support or base. The meehanismis illustrated in the accompanying drawings, in which- Figure I is a side view oft-he improved slateeraser. Fig. II is a central longitudinal sec- 2 tion of the same.

Similar letters designate like parts throughout the several views.

Ais a vessel having a cylindrical bore, and in the solid end, at the upper edge of the bore,

is a small orifice, S, and the opposite end is filled with the plug B, which remains per1nanently in position. A tapering bore is made in the center, which is filled by the stopplesupport 0. This part serves the double purpose of a base to support the eraser and to close the orifice through which the same is filled with water. To the ends are attached sponges, and the one on the right receives moisture from the interior through the aforesaid orifice. This end is used to erase the pen- ;0 oil-marks on a slate and the opposite end to effect the drying.

Imake no claim as to the hollow vessel with the sponges on the end, as in these features I am anticipated by others. The water is supplied through the orifice in the side of the vessel constituting the bottom, and opposite the orifice in the end, which is so situated as to prevent the water from escaping to the sponge while the same is supported by the base. The plug that closes this orifice in the bottom serves to supportthe same.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, 1S-

In an eraser, the combination or the hollow Us vessel A, a plugged end with sponge attached, and an orifice, S, in the solid end for the issue of water to a sponge attached thereto, and an orifice in the center of said vessel and opposite of said end orifice, and the stopplebase O, to close said orifice and to support said eraser, substantially as set forth.

In testimony that Iclaim the foregoing as my own I affix my signature in presence of two witnesses.

JOHN A. KIENARDT.
